Dealership; McCurley Integrity Chevrolet in Pasco, Washington.
I have never had a need to take my Camaro in for service yet, but I have bought two trucks from them, one gas and the second diesel. Both of those needed some work on them at some point and they were promptly repaired, no questions asked. I have always been treated with courtesy and respect by their friendly staff. Sales side shows the same type of commitment for their customers. Their moniker is "We never charge more than MSRP"
